To aZZ whom it may concern Be it known that I. .zlnnrn A. iloirroic, a citizen of the United States. residing at Detroit in the county of lVaQvne and State \of Michigan, have invented a certain new and useful Improvement in Adding-Machines, of which the following a specification.

The present invention relates to that type of adding machine commonly termed a. ten-key machine for the reason that. as distinguished from an adding maoine which has a series of keys :tor each order or denomination, the type oi machine in question employs but single set or noininational places,

@ne object of the present invention is to supply a machine ot-the above specified type which, while fully equipped for performing the (Bust-Omar) functions of the present-day adding machine such as'listing, adding, totaling, sub-totaling, repeating. printing without adding and adding without printing, may he of reduced size and weight as compared with most adding machines- A leading characteristic of the present machine which makes for reduction in size and number of parts. is the employment of h the number of stops ordinarily found necessary in the shifting carriage.

Thus in a machine having whatis known in the art as a nine-bank capacity. meaning nine numerical orders or denominational places, where ordinarily nine series each comprising ten steps would be n'iounted in the shifting carriage, making a total P" ninety stops the present invention makes it possible to obtain the same results with nine sets or series each composed of but five stops making a total of forty-five. This is accomplished in the machine presently to he described, by having the keys cooperate with the stops in pairs. one he oi a. pair moving the associated stop to a greater 'extent than the other key oitthe pair. and

the coljperatiug rclciprocatory accounting element having stepped abutment shoulders so that the stop measures the e. :cursi.ou of the accounting element by engagement with A. HORTON, 0F DETROIT, MICHIY HINE CDIHIPANY, OF DET'RGIT, HIGH Specification of Letters Patent.

one such shoulder when one key of a pair is operated and by engagement. with the other shoulder when the other key of a .pair is operated. the two shoulders being spaced apart a distance representing live steps in an order of numerals.

Va ious other characteristic features he present invention making for compactness of assemblage. convenience in manipulating. and accuracy and uniformity in operatii 1 will become amiar-ent as the detailed :tion of th present. form of embodiot' the invention proceeds. the accompanying drawings. sents a complete left side sec on of the machine: Fig. l" is a secdetail a type carrier: l ig. 2 a 'ht side sectional elevation some 0i mechanism removed.

Ewtcmml makeup.

The exterior of the machine comprises a base casting 1 on which are erected side irame pieces 2 and 3 for supporting the interior structure; and an inclosing case 4:

resting upon the base and having glass panels at the sides and a keyboard panel at the lower front portion where the casing slopes as illustrated most graphically in Fig. Amount keys 5 protrude through this portion of the casing and are arranged in two crosswise series of: five each making a total of ten keys which are numbered from zero to nine. Error and *epeat keys (5 and 7 protrude to the right of the amount keys and total and subtotal keys, 8 and 9 protrude to the left of the amount keys, this general relative location of keys being the most familiarto users of adding machines. A short distancev in rear of the above designated keys the casing has a vertical wall and above that a slightly sloping division. paneled for special keys and accumulator non-add and non-print keys 10 and 11 protruding through the right-hand panel and accumulator wheels 12 showing throu h the left-l1and panel. The upper part of the casing is arched symmetrically and has a centrally located bulging portion 4 paneled in triangular outline, a decimal place in- CllCZltOl' and an operation counter showing through thispanelh Just in rear. of the top arched poition of the casing is suitably mounted a roller platen 13 adjacent an opening 4- in the casing through which type carriers hereinafter described, may rise to pre sent their type at the printing position. The operating crank handle 1 L is located at the right as usual and detachably connected to its shaft.

Setting up mechanism.

The reciprocatory accounting elements are in the form of vertical slide bars 15, Figs. 1 to 5, 6, 8 and 11, suitably guided for root}- linear movement, flanged throughout their upper, portions to constitute housings 15 for type bars 16, and formed as racks 15 at their lower front portions. The lower roar portions of these slide bars have the stepped shoulders which cotiperate with the stops oi? the shifting carriage, as alrez dy mentioned. in the opening statement. Thus at the lower end' of each slide bar there is a horizontal shoulder 15 and upwardly therefrom a dis tance corrcspondii'ig with live numerical steps there is a similar shoulder 15 stepped forwardly with relation to the shoulder 15?. The shifting carriage comprises front and rear plates 17 and 17 connected by a bottom plate 17 which has guiding ears 17 straddling a frame cross rod 18. The top portions of these plates are tied together by clamping screws 19 which also secure in position an escapement rack 20, Figs. i and '5. Between the upper end portions of said carriage plates are mounted trolley rollers 21 which engage a rail 22 extending between and secured to the side frame pieces 2 and 3, this rail preferably being in the form of an inverted channel bar. The carriage plates in their depending portions have alining square openings, numbering forty-five in each plate and located to form nine vertical series of five each, Fig. 5. In these openings the denominational stop pins 23 are fitted to slide forward and back and each may advance for cooperation with either the shoulder 15 or the shoulder 15 of a slide bar 15. Normally of course they are all withdrawn out of the transverse vertical plane of the rearmost shoulders 15 as well as being removed laterally a step beyond the longitudinal vertical plane of the units slide bar (F ig. 5). The escapement mechanism by which, upon depression and release of an amount key. the carriage is caused to s. one step to bring the first vertical ser stop pins into line with the units ,slme har and so on, will be later described, it being understood of course that as usual in this type of machine successive depression of keys or of the same key will step the carriage over an extent corresponding with the denominational value of the amount being handled. Leaving the details of this escapement mechanism for description later on, I shall proceed to explain the control of
